The analysis has four parts. First, it will describe the level of adherence to the indicators in VA HIV patients nationwide and compare VA HIV patients to national benchmarks. Second, it will analyze facility and patient level predictors of adherence to indicators of quality of care and compare them with the predictors in the non VA population using staged logistic regressions. Third, it will seek to validate certain indicators (e.g. HAART therapy) against clinical outcomes like hospitalization and immune status. We will also model the clinical "price" that the VA pays in suboptimal clinical outcomes as a result of current performance levels. Fourth, we will compare the performance of the facilities after one year of an intensive targeted indicator-specific feedback group versus those receiving aggregate data only.
